Invitae RCV000467153 SCV000550989 uncertain significance Familial hypocalciuric hypercalcemia; Autosomal dominant hypocalcemia 1 2023-07-26 criteria provided, single submitter clinical testing ClinVar contains an entry for this variant (Variation ID: 410350). This variant has not been reported in the literature in individuals affected with CASR-related conditions. This variant is present in population databases (rs533567836, gnomAD 0.007%). This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 891 of the CASR protein (p.Arg891His). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
GeneDx RCV001764432 SCV002001072 uncertain significance not provided 2020-06-12 criteria provided, single submitter clinical testing Not observed at a significant frequency in large population cohorts (Lek 2016); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
